The Joint Research Centre (JRC) is a Directorate General of the European Commission (EC) that was founded as a result of the Treaty of Rome. It consists of seven institutes on five sites in Europe that have developed from an emphasis on nuclear research, to research in a wide range of fields of interest to European citizens. Here some aspects about nuclear research will be highlighted in the JRC and in the Institute for Reference Materials and Measurements (IRMM). Some examples will be given of recent nuclear data measurements.
